Activating persulfate by Fe0 coupling with weak magnetic field: Performance and mechanism

Modeling of Fe(II)-activated persulfate oxidation using atrazine as a target contaminant

“…Advanced oxidation processes (AOPs), a kind of in-situ chemical oxidation (ISCO) methods, have been extensively used for the remediation of groundwater and wastewater contaminated by a wide variety of recalcitrant organic matters, such as polychlorinated biphenyls [1], pharmaceutical and personal care products [2,3], pesticides [4][5][6], dyes [7,8], disinfection by-products and their precursors [9,10]. The conventional AOPs dominantly depend on the formation of reactive and non-selective hydroxyl radical (OH Å ) [11].…”

Effective Sb(V) immobilization from water by zero-valent iron with weak magnetic field

“…However, the immobilization of Sb(V) by ZVI has seldom been investigated. Our previous study showed that the application of a weak magnetic field (WMF) could promote ZVI corrosion, resulting in more rapid release of Fe 2+ and greater sequestration of As(V), As(III), Se(IV), and Cu(II) [29][30][31][32]. Therefore, this study proposed to employ ZVI coupled with WMF to achieve the effective immobilization of Sb(V).…”

Catalytic degradation of bisphenol A by CoMnAl mixed metal oxides catalyzed peroxymonosulfate: Performance and mechanism

“…It has been reported that PMS can be activated to generate sulfate radicals by UV, heat, ultrasound, base, granular activated carbon or transition metals [10]. Wang et al [11] fabricated three kinds of one-dimensional a-MnO 2 nanostructures including nanorods, nanotubes and nanowires, which were used as heterogeneous catalysts to activate PMS for phenol degradation.…”
